Destination sensitive Services

[mbakman]

We would like to setup a class-map that matches certain destinations. All these destinations should be in our BGP route tables with a certain AS number in their as-pathlist. Basicly we would like to match all traffic that is going to be sent through a certain AS by our ISP. Looking at this doc http://www.cisco.com/en/US/customer/products/hw/routers/ps368/products_module_configuration_guide_chapter09186a008007cb27.html

We can do this by a route-map that matches a community.

What I would like to know is can we match an as-path instead of a community like this?

route-map set_bucket

match as-path 1

set traffic-index 1

Since this is similar to QoS Policy propagation through BGP, and BGP policy accounting feature which can mark or account based on AS path, I would think that you could match this as well based on AS-path. These links should give you some idea :
